Definitions
- the invention relates to a floating gripper system for the extraction of sand and gravel with a trestle arranged on a floating body, possibly catamaran-like floating body, for a trolley system which has a horizontally movable cat with a gripper, a container being attached to the floating body in which the a bucket excavator led diagonally upwards.
- An excavator is known (US-A-4 231 172), in which a pair of collecting containers are arranged on a floating body and are provided with bucket-chain excavators. These lead obliquely upwards from the lowest point of a container. Furthermore, a trolley system is provided on the pontoon on a trestle frame, namely consisting of several grippers that can be moved next to one another, which bring the material into the containers, where it is then transferred from the bucket excavators to a further processing system.
- the disadvantage of this device is that the grippers have to be pulled very high above water in order to transfer the excavated material to the container. Most of the energy is consumed here, which reduces the output. If the material is dirty and muddy, it is hardly possible to dose it exactly to the dewatering machine.
- an excavator (DE-C-37 496) in which an underwater container is attached to two floating bodies, so that these two floating bodies and the container form a unit.
- a bucket excavator which runs diagonally upwards, dips into this container and extends to the lowest point of the container. Between Both floats form a channel for the supply of material into which folding barges can enter, where they unload their material which is conveyed out of the container by the bucket excavator that is pulled upwards when a folding barge is pulled in.
- Such an excavator is only suitable for unloading folding barges, with the underwater container having a length corresponding to the folding barge. The material is then transported ashore by the bucket excavator.
- the container used is not suitable as a classifying device, ie for processing material that can be processed, eg material containing sludge.
- the invention has for its object to provide a floating gripper system of the known type so that the underwater tank is suitable as a classifying device for conveying reprocessable material while achieving an energy saving and increasing the conveying capacity.
- the container arranged on the float is an underwater container, that the underwater container is designed as an upstream container with spray nozzles, and that an all-round overflow channel is arranged on the upper edge of the container on the water line which is connected to an outlet gutter.
- An advantageous embodiment consists in that the gripper is arranged on a jib crane system with a jib that can be extended and retracted and that it can be pivoted into the area of the container.
- the gripper arranged on a stationary hoist is mounted above a horizontally movable bunker wagon of a bunker wagon system, the bunker wagon being movable into the area of the container.
- a tilting or scratching grate is arranged between the gripper and the underwater tank.
- An advantageous embodiment provides that the underwater tank is connected to the tilting or scratching grate by means of a funnel, the side walls of which are directed as a chute against the tank bottom.
- the invention has the advantage that the gripper does not have to be lifted out of the water or the lifting height of the gripper above water is considerably reduced. Combined with the processing plant, this results in high energy savings of around 40% compared to conventional plants, as well as an increase in conveying capacity of at least 10%.
- the height of the downstream dewatering machine and the dosing silo is bridged with the bucket ladder.
- the bucket ladder enables exact dosing onto the drainage sieve or the conveyor belts.
- the speed can be adapted to the dredged material.
- a large storage silo can be omitted.
- the dredged material lies in an underwater tank and has natural buoyancy, which benefits the floating position of the system.
- the gravel drainage and desludging can be adjusted more easily than the known desludging machines and can always be easily adapted to the dredged material due to the amount and pressure of the upstream water. Overall, this results in an improved efficiency in the floating gripper system and a desludging with the least effort.
- a trestle frame 2 with a horizontally movable trolley system 3 on which a gripper 4 is arranged.
- An underwater or collecting tank 7 is attached to the floating body 1.
- This container 7 is located below the water level 8, a bucket excavator 9 or bucket ladder being immersed in the bottom 15 of this container, which is guided obliquely upwards.
- the material discharged from the bucket excavator 9 reaches a swimming belt 14 via a slide 21.
- This embodiment is particularly suitable for well dredged material in which no larger boulders, tree trunks and the like. Like. Are present. This results in optimal energy savings since the gripper is not lifted out of the water.
- the underwater tank 7 is designed as an upflow tank, the undesirable fine sand and fossil Components are discharged by metered amounts of water and by pressure.
- a tube 16 with inflow nozzles, which is connected to a pump 17, is located on the side wall 11, which runs obliquely to the container base 15, and the container base 15.
- a tilting or scratching grate 5 is arranged on the floating body 1 and is connected to the underwater container 7 via a funnel 6.
- the side walls 10 and, above all, 11 of the funnel 6 act as a chute for the material fed in via the grate.
- the bucket excavator is followed by a drainage screen 13, from where the material reaches the swimming belt 14.
- an overflow channel 18 attached to the side of the water line on the tank 7 serves to collect these components which have been washed up and pass through an outlet channel 18 'into a sump pump tank 19 with underwater pump 20, from where they are ashore or transported to dredged places in the lake.
- the material discharged from the bucket excavator 9 passes via a slide 21 to the drainage sieve 13, the underflow of the drainage machine 13 being connected to the underwater tank 7 via a return channel 22, so that generally usable sand can be returned to the circuit.
- the fine material falling on the lower run of the bucket excavator 9 is fed back to the container 7 via the inclined wall 31 acting as a chute and is thus subject to the further processing process.
- the bucket ladder excavator 9 is pivotally arranged on the upper roller 23 on a stationary bearing, while the lower end is arranged on a lifting winch 24, so that the inclination can be adjusted. Furthermore, the grate 5 is provided with a slide 25 for oversize particles (FIG. 5).
- the floating body 1 is designed as a catamaran-like floating body, the floating gripper system otherwise having the same features as the system shown in FIGS. 1 and 2 or FIGS. 3 to 6.
- a jib crane system 26 is provided instead of a trolley system, the gripper 4 being arranged on a boom 27 that can be extended and retracted.
- FIG. 9 shows a floating gripper system in which the gripper 4 or possibly also a double gripper is arranged on a rigid winch 28.
- the tipping or scraper grate 5 is arranged on a bunker wagon 29 which can be moved on a track 30 and can be moved to the funnel 6 in the used position.

Abstract
Description
Die Erfindung betrifft eine Schwimmgreiferanlage für die Gewinnung von Sand und Kies mit einem an einem Schwimmkörper, ggf. katamaranartigen Schwimmkörper, angeordneten Bockgerüst für eine Katzanlage, die eine horizontal verfahrbare Katze mit Greifer aufweist, wobei an dem Schwimmkörper ein Behälter angebaut ist, in den am tiefsten Punkt ein schräg nach oben geführter Eimerbagger eintaucht.The invention relates to a floating gripper system for the extraction of sand and gravel with a trestle arranged on a floating body, possibly catamaran-like floating body, for a trolley system which has a horizontally movable cat with a gripper, a container being attached to the floating body in which the a bucket excavator led diagonally upwards.
Es ist ein Baggerapparat bekannt (US-A-4 231 172), bei dem auf einem Schwimmkörper ein Paar von Auffangbehältern angeordnet sind, die mit Eimerkettenbaggern versehen sind. Diese führen vom tiefsten Punkt eines Behälters schräg nach oben. Weiterhin ist auf dem Ponton an einem Bockgerüst eine Katzanlage vorgesehen und zwar bestehend aus mehreren, nebeneinander verfahrbaren Greifern, die das Material in die Behälter bringen, wo es dann von den Eimerbaggern an eine Weiterverarbeitungsanlage übergeben wird. Der Nachteil dieser Einrichtung besteht darin, daß die Greifer sehr hoch über Wasser gezogen werden müssen, um das gebaggerte Material an den Behälter zu übergeben. Hier wird die meiste Energie verbraucht, wodurch die Förderleistung vermindert wird. Bei verschmutztem und verschlammtem Material ist eine exakte Dosierung auf die Entwässerungsmaschine kaum möglich.An excavator is known (US-A-4 231 172), in which a pair of collecting containers are arranged on a floating body and are provided with bucket-chain excavators. These lead obliquely upwards from the lowest point of a container. Furthermore, a trolley system is provided on the pontoon on a trestle frame, namely consisting of several grippers that can be moved next to one another, which bring the material into the containers, where it is then transferred from the bucket excavators to a further processing system. The disadvantage of this device is that the grippers have to be pulled very high above water in order to transfer the excavated material to the container. Most of the energy is consumed here, which reduces the output. If the material is dirty and muddy, it is hardly possible to dose it exactly to the dewatering machine.
Bekannt ist weiterhin ein Baggerapparat (DE-C-37 496), bei dem an zwei Schwimmkörpern ein unter Wasser liegender Behälter befestigt ist, so daß diese beiden Schwimmkörper und der Behälter eine Einheit bilden. In diesen Behälter taucht ein schräg nach oben geführter Eimerbagger ein, der bis zum tiefsten Punkt des Behälters reicht. Zwischen den beiden Schwimmkörpern wird für das Zuführen von Material eine Fahrrinne gebildet, in die Klappschuten gelangen können, die dort ihr Material entladen, das von dem Eimerbagger, der beim Einfahren einer Klappschute nach oben gezogen wird, aus dem Behälter herausgefördert wird. Ein derartiger Baggerapparat ist lediglich zum Entladen von Klappschuten geeignet, wobei der Unterwasserbehälter eine der Klappschute entsprechende Länge aufweisen muß. Das Material wird dann von dem Eimerbagger an Land gefördert. Dabei ist der verwendete Behälter nicht als Klassiereinrichtung geeignet, d.h. zum Verarbeiten von aufbereitungsfähigem Material, z.B. schlammhaltigem Material.Also known is an excavator (DE-C-37 496) in which an underwater container is attached to two floating bodies, so that these two floating bodies and the container form a unit. A bucket excavator, which runs diagonally upwards, dips into this container and extends to the lowest point of the container. Between Both floats form a channel for the supply of material into which folding barges can enter, where they unload their material which is conveyed out of the container by the bucket excavator that is pulled upwards when a folding barge is pulled in. Such an excavator is only suitable for unloading folding barges, with the underwater container having a length corresponding to the folding barge. The material is then transported ashore by the bucket excavator. The container used is not suitable as a classifying device, ie for processing material that can be processed, eg material containing sludge.
Der Erfindung liegt die Aufgabe zugrunde, eine Schwimmgreiferanlage der bekannten Art so auszubilden, daß unter Erzielung einer Energieeinsparung und Förderleistungs-Steigerung der Unterwasserbehälter als Klassiereinrichtung zur Förderung von aufbereitungsfähigem Material geeignet ist.The invention has for its object to provide a floating gripper system of the known type so that the underwater tank is suitable as a classifying device for conveying reprocessable material while achieving an energy saving and increasing the conveying capacity.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß der an dem Schwimmkörper angeordnete Behälter ein Unterwasserbehälter ist, daß der Unterwasserbehälter als Aufstrombehälter, mit Sprühdüsen versehen, ausgebildet ist, und daß am oberen Rand des Behälters an der Wasserlinie eine ringsumlaufende Überlaufrinne angeordnet ist, an die eine Auslaufrinne angeschlossen ist.This object is achieved according to the invention in that the container arranged on the float is an underwater container, that the underwater container is designed as an upstream container with spray nozzles, and that an all-round overflow channel is arranged on the upper edge of the container on the water line which is connected to an outlet gutter.
Eine vorteilhafte Ausführungsform besteht darin, daß der Greifer an einer Auslegerkrananlage mit auslegbarem und einziehbarem Ausleger angeordnet ist und in den Bereich des Behälters schwenkbar ist.An advantageous embodiment consists in that the gripper is arranged on a jib crane system with a jib that can be extended and retracted and that it can be pivoted into the area of the container.
Weiterhin geht man so vor, daß der an einem stationären Hubwerk angeordnete Greifer oberhalb eines horizontal verfahrbaren Bunkerwagens einer Bunkerwagenanlage angebracht ist, wobei der Bunkerwagen in den Bereich des Behälters verfahrbar ist.Furthermore, one proceeds in such a way that the gripper arranged on a stationary hoist is mounted above a horizontally movable bunker wagon of a bunker wagon system, the bunker wagon being movable into the area of the container.
Es wird weiterhin vorgeschlagen, daß zwischen dem Greifer und dem Unterwasserbehälter ein Kipp- oder Kratzrost angeordnet ist.It is further proposed that a tilting or scratching grate is arranged between the gripper and the underwater tank.
Eine vorteilhafte Ausführungsform sieht vor, daß der Unterwasserbehälter mittels eines Trichters zum Kipp- oder Kratzrost angeschlossen ist, dessen Seitenwände als Schurre gegen den Behälterboden gerichtet sind.An advantageous embodiment provides that the underwater tank is connected to the tilting or scratching grate by means of a funnel, the side walls of which are directed as a chute against the tank bottom.
Es ist vorteilhaft, daß an dem Schwimmkörper ein Pumpensumpf angeordnet ist.It is advantageous that a pump sump is arranged on the floating body.
Weiterhin geht man so vor, daß dem Eimerbagger eine Entwässerungsmaschine nachgeschaltet ist.Furthermore, one proceeds in such a way that the bucket excavator is followed by a dewatering machine.
Schließlich wird vorgeschlagen, daß das an der Entwässerungsmaschine anfallende Feinmaterial über eine Schurre zum Unterwasserbehälter geleitet wird.Finally, it is proposed that the fine material accumulating on the dewatering machine be guided to the underwater tank via a chute.
Die Erfindung bringt den Vorteil, daß der Greifer nicht aus dem Wasser gehoben werden muß bzw. die Hubhöhe des Greifers über Wasser erheblich reduziert wird. Verbunden mit der Aufbereitungsanlage ergibt sich gegenüber herkömmlichen Anlagen eine hohe Energieeinsparung, die in der Größenordnung von 40 % liegt sowie eine Förderleistungssteigerung von wenigstens 10 %. Hierbei wird die Bauhöhe der nachgeschalteten Entwässerungsmaschine und des Dosiersilos mit der Eimerleiter überbrückt. Durch die Eimerleiter ist eine exakte Dosierung auf das Entwässerungssieb bzw. die Förderbänder möglich. Durch veränderliche Geschwindigkeit kann eine Anpassung an das Baggergut erfolgen. Ein großer Vorratssilo kann entfallen. Das Baggergut liegt in einem Unterwasserbehälter und hat natürlichen Auftrieb, was der Schwimmlage der Anlage zugute kommt. Weiterhin läßt sich die Kies-Entwässerung und -Entschlämmung gegenüber den bekannten Entschlämmungsmaschinen einfacher und durch die Menge und den Druck des Aufstromwassers auch stets dem Baggergut leicht anpassen. Insgesamt ergibt sich somit ein verbesserter Wirkungsgrad, bei der Schwimmgreiferanlage sowie ein Entschlämmen mit geringstem Aufwand.The invention has the advantage that the gripper does not have to be lifted out of the water or the lifting height of the gripper above water is considerably reduced. Combined with the processing plant, this results in high energy savings of around 40% compared to conventional plants, as well as an increase in conveying capacity of at least 10%. The height of the downstream dewatering machine and the dosing silo is bridged with the bucket ladder. The bucket ladder enables exact dosing onto the drainage sieve or the conveyor belts. The speed can be adapted to the dredged material. A large storage silo can be omitted. The dredged material lies in an underwater tank and has natural buoyancy, which benefits the floating position of the system. Furthermore, the gravel drainage and desludging can be adjusted more easily than the known desludging machines and can always be easily adapted to the dredged material due to the amount and pressure of the upstream water. Overall, this results in an improved efficiency in the floating gripper system and a desludging with the least effort.
